chore: rename workspace dirs to packages/${package-base-name} (extreme edition)

[trentm]

This is take 2 of #2223
This implements option 3 of #2223 (comment)
(i.e. the "extreme" option)

Status

DO NOT MERGE

Let's not merge this yet, even if agreed on doing this. I think we can finish the instr-redis consolidation, and drop the redis-common package first.
